This paper elucidates a key puzzle related to texture randomization - effect of rare earth on grain boundaries. We use electron back-scatter diffraction and molecular dynamics to compare recrystallization between pure Mg and a Y-containing alloy. The

Basal slip and dynamic recovery of dislocations have been long assumed as the main mechanisms accounting for the sharp texturing of magnesium alloys upon dynamic recrystallization at high temperature. Basal slip allows the basal plane to mitigate str

The origin of texture components often associated with rare-earth element (REE) additions in wrought magnesium alloys is a long-standing problem in magnesium technology. While their influence on the texture is unquestionable, it is not yet clear why

Effect of the Zener–Hollomon parameter on the microstructure evolution of dual phase TWIP steel subjected to friction stir processing

Autor: M.H. Razmpoosh, Aidin Imandoust, A. Zarei-Hanzaki

Publikováno v: Materials Science and Engineering: A. 638:15-19

The present work is devoted to investigate the correlation between the Zener–Hollomon parameter and the grain structure of the thermo-mechanically processed dual phase twinning induced plasticity (TWIP) steel utilizing the friction stir processing
